According to WikiAnswers, the proper battery for a Maxim 400 (the Seca's sister) is 12N 12A-4A. I'm looking for one also. This is the same battery I used in my '72 Yamaha XS650 although it had a "-1" designation at the end.
12 volts
6 volts
What is the tire pressure for 1982 Yamaha xj550 Maxim
i need to buy a service manual for a 1982 yamaha maxim 400
A Yamaha Maxim 650 motorcycle has a 4-cylinder engine. The Yamaha Maxim 650 will hold 3.1 quarts or 2.65 milliliters of oil with the oil filter attached.

More than likely a defective voltage regulator.
Originally the maxim was a cruiser and the xj a tourer. Later the xj 650 maxim was a bit of both. There are many through-the-ages examples on google images.
1982 and 1983
A Honda shadow sissy bar usually will not fit a Yamaha maxim 650. You will need to purchase the exact sissy bar fit from a Yamaha manufacture.
